The FDA has made an advisory against the off-label use of magnesium sulfate to stop pre-term labor in pregnant women for more than 5 – 7 days, and added a new warning about possible harm to the developing baby.

Use of magnesium sulfate in pregnant women for longer than 5 – 7 days can lead to low calcium levels and bone problems in the developing baby, including thin bones and fractures.

Magnesium sulfate may be used to prevent and control seizures in pregnant women with eclampsia. However, use over a longer period to prevent pre-term labor isn’t an approved indication, and may cause harm to the baby.
